HYDRANT.

SPECIFICATION forming part of Letters Patent No. 587,364, dated August 3, 189'?.

Application filed April 15,1895.

T0 all whom. it may concern:

Be it known that I, FRANK M. FARWELL, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Hydrants, of which the following is a specication.

My invention relates to improvements in hydrants, its object being to provide independent plug or nozzle cut-offs by means of which water may be drawn from the hydrant through one plug-opening independently of the main valve and of the other plug.

To this end my invention consists in providing for each plugopening an interior sleeve or collar, preferably provided with a double valve-seat, which sleeve is anchored in the opening by means of soft-metal filling, so as to be fixed rigidly in place. I also provide a second sleeve slidably arranged within the first or fixed sleeve and carrying a double valve fitted to the seat in the fixed sleeve, whereby the plug may be opened and closed and the water shut off from around the sleeve when the plug is opened. The slidable sleeve is operated by means of a collar-nut threaded thereon and having a groove-and-flange connection with the plug or fixed sleeve. The hose is connected directly to the slidable .sleeve beyond the nut, and the turning of the nut drives the sleeve to open or close the plug.

My invention further consists inthe construction `and combination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure l is a front elevation of a hydrant fitted with my improved attachment. Fig. 2 is a vertical central section of the hydrant through the plug, showing the valve construction, the valve being open. Fig. 3 is an enlarged sectional detail of the plug and cut-o valves, taken on line om of Fig. 2 and showing the valve closed. Fig. 4L is a cross-section of the same, taken on line 'y y of Fig. 3. Fig. 5 is a sectional detail corresponding to Fig. 3 of a modified construction, and Fig. 6 is a detail of a modified form of guide for the valve-carrying arms.

In the drawings, A represents a hydrant of ordinary type, provided with the rod 2 for operating the main cut-off valve (not shown) and having one or more plugs 3.

Arranged within the plug-fiange 4 is the sleeve 5, provided with a circumferential rib Serial No. 545,685. (No model.)

is secured the valve 13, fitted to the innerA face of the double valve-seat 8. It will thus be seen thatwhen the valve is thrust inward or into open position the water from the hydrant will pass through the space between the standards or arms carrying the valve and thence through the sleeve tothe connected hose. The sleeve 9 is also fitted with the valve 14, which is adapted when Athe sleeve is driven inward to fit to the outer face of the valve-seat. This prevents the flow of water into the space between the two sleeves.

In order to prevent the sleeve 9 from rotating, I provide it with studs or screws 15, which travel in grooves 16 in the inner wall of the sleeve 5, as shown in Figs. 3Iand 4, or, as shown in Figs. 5 and 6, the standards or arms -11 may be fitted to notches 17 in the flange 18 between the two faces ofA the double valve-seat. In order to operate the sleeve 9 so as to open and close the valve 13, I provide the collarnut 19, having outwardly-projecting studs 20, threaded upon the sleeve, and held in engagement with the plug of the hydrant by means of the flange 21, engaging a similar flange 22 upon the collar 23, threaded or otherwise sewater in the space between the two sleeves may be employed, such as a narrow vent 25 through the wall of the sleeve 5, as shown in FiO. 5.

'he valve 13 stands normally open, the water bein gpcut off from the hydrant by the clos- IOO ing of the main valve, and the plug being- When required for i valve 14E preventing the flow of water between the sleeves. While the main valve remains open, to supply a second'nozzle or for anyA other reason'the valve 13 may be closed by screwing the collar-nut to drive the sleeve outward, so as to shut o the flow of water through the plug.

I claiml. In a hydrant, the combination with its l lateral plug, of the sleeve or collarslidable in said plug, and the double valve and valveiXed parts of said plug whereby leakage seat connection between said sleeve and the l around said sleeve is prevented in both open E and closed positions thereof.

2. In combination with a hydrant plug o-r nozzle, the lsleeve arranged therein, Vmeans for .slidably adjusting its position, and the double valve and valve-seat connection bef tween said sleeve and plug whereby leak-age ent adjusted positions.

3. In a hydrant, the combination with its i lateral plug, ofthe sleeve or collar xed in i said plug, the slidable sleeve arranged within said fixed sleeve, and the double valve and valve-seat connection between the fixed and l slidable sleeves.

4;. In combination with a hydrant plu-g or j nozzle, the sleeve fitted to said plug, the softi metal illing anchoring the sam-e therein., the 3 slidable sleeve adj ustably arranged Ain said first sleeve, the valve and valve-seat, one car- 3 ried by said slidable sleeve and the other;

upon the fixed sleeve, and the collar having f a circumferential groove and iiange connec- .Y

tion with said fixed sleeve `and threaded upon j,

said slidable sleeve.

5. 4In a hydrant, the combination with its 1 lateral plug, of the fixed double valvejseat ar- 1 ranged therein, the sliding sleeve, the valve g carried by said sleeve and fitted to the inner g valve-seat so as to close the plug, and the secl ond valve carried by said sleeve and adapted 5 to be seated upon the outer valve-seat when f the inner valve is open, so as to prevent leakage around the sleeve.

6. In a hydrant, the combination with the lateral plug, of the valve-seat arranged therecarried by inwardly-projecting arms Yupon said s1eeve,and fitted to said seat to close said plug, the oppositely-arranged valve-seat in said plug, and the second valve carried by said sleeve fitted to said second seat and adapted to cut off the fioW of water from the hydrant around said sleeve when the first Valve is open. b i 7. In a hydrant, the combination with its` lateral plug,.of the sleeve or collar fixed Within the plug-ilange and provided with a double valve-seat, the sleeve slidable within said fixed sleeve and carrying valves, and fitted to said seats, the one to close the plug and the other to cut ohc the flow of water between said sleeves when the-other valve is open.

8. In a hydrant, the combination with its lateral plug, of the sleeve fixed within the flange of the plug, the double valve-seat Within said sleeve, the second sleeve slidable within said first sleeve, the pair of valves carried by said second sleeve and adapted to be seated by its movement the one to close the plug and the other to cut off the flow-fof water between the sleeves when the plug is open, vand the eollarhavingjournal connection with the plug, and threaded upon said inner sleeveso as to drive the same inward or outward.

9. 4In a hydrant, the combination with its lateral plug, of the sleeve fixed iu said plug and provided with a double valve-seat, the `eX- teriorly-.threaded sleeve :slidable within said iirstsleeve, the valves carri-ed thereby adapted to be closed against their respective seats, the collar nut threaded upon said second sleeve and having freely-turning engagement with the plug, whereby when operated it serves to ydrive the sleeve inward or outward i according to the direction `of its rotation.

In testimony whereof I Vafin my signature in presence of two witnesses.
